STOVE-PIPE COUPLING.

SPECIFICATION forrnng part of Letters Patent No. 376,026, dated January 3, 1888.

Y Application lerl July 9, 1887. Serial o. 243,856. (No model.)

To cl/ZZ whom. it may concern:

Be it known that I, ANGUs CAMPBELL, of Powassan, in the district of Parry Sound, in the Province of Ontario, Canada, haveinvented certain new and useful Improvements in Stove- Pipe Couplings; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to bands to connect two sections of ordinary stove pipe when not telescoped together, and has for its object to draw the coupling-band tightly around the pi pesections by means of a lever, and by a continuing motion of the lever lock the ends ofthe band together bya bar at one end of the band engaging a catch near the other end, as hereinafter described.

Figure lis an elevation of two sections of stovepipe coupled by my improved band, the band being shown as brok-en away, so that the ends of the pipe sections and theswage may be seen. Fig. 2f is a longitudinal section of the band as on line x x, Fig. 3, curved and unlocked; and Fig 3 is a diagram of the outside of the band.

A A are two sections of stove-pipe provided with theusual swages, B B.

O is my improved tlexibe sheetnietal coupling-band, having longitudinal swages D D, which coincide with the swage B of the pipes when the band is tightened around the sections to cover the joint and prevent separation of the sections. The band C has a slot at one end crossedV by a bar, F, which is held by the end ofthe band being turned over thebar and riveting the doubled metal.

G is a catch riveted to near the other end of the band, so that the end of the band will lap when drawn around the stove-pipe sections, and said catch has jaws H, through which are inserted crosswise a bar, I, and said jaws are notched at the rear to engage bar F.

` The couplingband is tightened around the two sections of stovepipe by inserting one end ofa lever through the slotted opening under bar F and over fulcrunrbar I, so that by lifting the lever from a tangential to a radial position with respect to the stove-pipe the ends of the coupling-band will be drawn together and bar F will slip down the lever and engage with the jaws H, thus effecting coupling of the pipe-sections A A by locking the ends of the band together.

To unlock the coupling-band thelever is inserted over bar Iand under bar F and pried.

I Vclaim as my invention- Q A stove-pipe coupling consisting of a band provided with two longitudinalparallel swages and having a slot at one end crossed by a bar and at the other end a catch having notched jaws connected by a fulcrurn-bar, whereby the band can be drawn around a stove-pipejoint by a lever and the ends locked together, as set forth. Y

ANGUS CAMPBELL.
